%% Unwrap input phase data %% % *Note*: This example runs only in R2016b or later. If you are using an % earlier release, replace each call to the function with the equivalent % |step| syntax. For example, myObject(x) becomes step(myObject,x). %% hunwrap = dsp.PhaseUnwrapper; p = [0 2/5 4/5 -4/5 -2/5 0 2/5 4/5 -4/5 -2/5 0 2/5 ... 4/5 -4/5, -2/5]*pi; y = hunwrap(p'); figure,stem(p); hold stem(y, 'r'); legend('Input (blue)','Unwrapped data (red)'); hold off;
